“…In the presence of two and more longitudinal modes, long period modulation gratings of second type appear on a scale fixed by the frequency difference between each pair of the interacting modes. Such "phase-sensitive" gratings were introduced (for example [13]), to obtain a better relation between theory and experiments in dual longitudinal mode lasers. In this paper, we show that a similar approach can be developed to account for the experimental observations of the laser polarization dynamics.…”

UDC 621.373This paper is devoted to the polarization dynamics of a longitudinally monomode bipolarized Nd:YAG laser: the low-frequency polarization dynamics of a microchip laser is studied experimentally and theoretically. The intensities and the relaxation oscillation spectrum of orthogonally polarized modes versus the direction of pump polarization is observed. A phase-sensitive model of a longitudinally monomode bipolarized solid-state laser with linear polarized diode laser pump is developed to account for the experimental observations.

“…Strictly speaking, rate-type equations are inapplicable under such conditions. In this case, one should use models taking into account the phase-sensitive coupling of the modes [28][29][30] by virtue of the oscillating populationinversion grating induced by their joint action. The presence of phase-sensitive coupling drastically changes the physical picture of processes in the laser.…”

We discuss the problem of excess noise in lasers of different dynamical classes, as well as adequate models for the description of such noise. It is shown that the excess noise in lasers is caused by mode-mode coupling. The linear coupling leads to the phenomenon of excess noise in the narrow sense (Petermann's excess noise), while the nonlinear mode coupling is the universal mechanism for excess noise of dynamical nature. It is shown that the theory of excess noise in class-B lasers does not require new approaches and can be developed on the basis of models with adiabatically eliminated polarization obtained in a standard way.

“…Therefore, longitudinal variations of the carrier density will be washed out by the diffusion. As a result, the dynamics of such a carrier grating can be neglected [2,11,12]. However, a linear coupling between the two counter-propagating modes does exist.…”
